Public COA audit
Tirzepatide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 88%
- Panels
- 2/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "Sterility-only report". To improve: include identity, purity, and endotoxin at minimum and prefer labs with a public verification portal.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Tested · passed
Bioburden / microbial limits testing.
Bacteria: No Growth; Fungi/Yeast: Not Detected
Endotoxin
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Sterility
Tested · passed
Sterility testing where applicable.
No microbial growth detected
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Sterility-only report
This is a sterility screening report only. No identity, purity, endotoxin, heavy metals, or residual solvent testing is included. This appears to be a supplemental test report, not a comprehensive COA.
Rapid screening method
Document explicitly states this is a 'rapid screening method' (2-day incubation) for 'preliminary sterility assessment' and notes that 'full USP <71> sterility testing may be required' for regulatory compliance. This is not a full pharmacopeial sterility test.
Lab verification not possible
Kovera Labs is not a widely recognized third-party testing laboratory in peptide/pharmaceutical testing. No website URL, accreditation information, or independent verification method is provided beyond a QR code access code.
Batch number present
Lot number TZ202605 is clearly stated and matches the vial image shown.
Same-day turnaround
Sample received and certified on the same day (06/09/2026). While rapid for sterility, this is consistent with a 2-day rapid screening method if the report generation occurred after incubation.
Professional presentation
Document has professional layout, clear branding, structured data presentation, and includes a product photograph with visible batch number.
